“And how you wouldn’t take off some kind of hat for 2 years straight and how we would obsessively read books about sharks together( and you still remember the 7 deadliest sharks 🦈),” she added. “I look at you today from across a room and wonder how I got so blessed. 🙏🏼 You are kind,thoughtful,mature and beautiful inside and out. I love you bruh 🧢🐒🎉🧡🎇🫶.”

“Crazy!!!! Happy b day Mikey 🙌❤🙌,” Wahlberg commented under the post.

Michael’s milestone birthday comes after, in recent interview with PEOPLE, his actor father shared that after moving from California to Las Vegas in 2022, he and his family are all settled in and doing well — his children in particular.

“It’s a place where my kids can thrive and do their thing and pursue their interests,” he told PEOPLE earlier this month.
